Alfred would be really cool IMO, but in the Matty Batman forum, it was said that the other 3 figures could not be revealed until they have "permission from WB".

I bet that if there's a Joseph Gordon-Levitt's figure using his cop uniform, it would have not be a problem (spoiler) showing the figure. The same aplies to Alfred. But if they sculpted Ra's figure or a venon superpowered Bane, they would not be able to show it by now...
